https://notcve.org/view.php?id=CVE-2018-14318

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Samsung Galaxy S8 G950FXXU1AQL5. User interaction is required to exploit this vulnerability in that the target must have their cellular radios enabled. The specific flaw exists within the handling of IPCP headers.
